Ipomoea plant named ‘Fnpalligr’

ABSTRACT

A new and distinct cultivar of  Ipomoea  plant named ‘Fnpalligr’, characterized by its compact, upright and mounding plant habit; freely branching habit and short internodes, dense and bushy growth habit; and medium to small light green-colored palmate-shaped leaves.

Botanical designation: Ipomoea batatas.

Cultivar denomination: ‘FNPALLIGR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ipomoea plant, botanically known as Ipomoea batatas, and hereinafter referred to by the name ‘Fnpalligr’.

The new Ipomoea plant is a product of a planned breeding program conducted by the Inventor in Lompoc, Calif. The objective of the breeding program is to create new compact and freely branching Ipomoea cultivars with attractive foliage shape and coloration.

The new Ipomoea plant originated from an open-pollination during the autumn of 2007 of an unnamed proprietary selection of Ipomoea batatas, not patented, as the female, or seed, parent with an unknown selection of Ipomoea batatas as the male, or pollen, parent. The new Ipomoea was discovered and selected by the Inventor as a single plant within the progeny of the stated open-pollination in a controlled greenhouse environment in Lompoc, Calif. in March, 2008.

Asexual reproduction of the new Ipomoea plant by terminal cuttings in a controlled greenhouse environment in Lompoc, Calif. since April, 2008, has shown that the unique features of this new Ipomoea plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Ipomoea have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Fnpalligr’. These characteristics in combination distinguish ‘Fnpalligr’ as a new and distinct cultivar of Ipomoea:

-   -   1. Compact, upright and mounding plant habit.     -   2. Freely branching habit and short internodes, dense and bushy         growth habit.     -   3. Medium to small light green-colored palmate-shaped leaves.

Plants of the new Ipomoea can be compared to plants of the female parent selection. Plants of the new Ipomoea differ from plants of the female parent selection in the following characteristics:

-   -   1. Leaves of plants of the new Ipomoea are more lobed than         leaves of plants of the female parent selection.     -   2. Plants of the new Ipomoea have light green-colored leaves         whereas plants of the female parent selection have dark         purple-colored leaves.

Plants of the new Ipomoea can be compared to plants of the Ipomoea batatas ‘Sweet Caroline Sweetheart Light Green’, disclosed in U.S. Plant Pat. No. 18,572. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new Ipomoea differed from plants of ‘Sweet Caroline Sweetheart Light Green’ in the following characteristics:

-   -   1. Plants of the new Ipomoea were more freely branching than         plants of ‘Sweet Caroline Sweetheart Light Green’.     -   2. Plants of the new Ipomoea had shorter internodes and were         bushier and denser than plants of ‘Sweet Caroline Sweetheart         Light Green’.     -   3. Plants of the new Ipomoea had smaller leaves than plants of         ‘Sweet Caroline Sweetheart Light Green’.     -   4. Plants of the new Ipomoea had palmate-shaped leaves whereas         plants of ‘Sweet Caroline Sweetheart Light Green’ had         cordate-shaped leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Ipomoea plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Ipomoea plant.

The photograph at the bottom of the sheet comprises a side perspective view of typical plants of ‘Fnpalligr’ grown in a container.

The photograph at the top of the sheet comprises a close-up view of typical leaves of ‘Fnpalligr’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Lompoc, Calif. in a polyethylene-covered greenhouse during the summer and under conditions which closely approximate commercial Ipomoea production. During the production of the plants, average day temperatures were 22° C. and average night temperatures were 17° C. Plants were grown in 15-cm containers and were six weeks old when the photographs and description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
